I guess I didn't make my point very clearly. What I said was I
personally would not use GOTOs "as part of the overall control
structure of the program" [meaning at the highest-most decision-
making levels], but *possibly* would use them in some "low-level"
routines that perform certain specific and limited operations.

For overall program flow control, there are certainly much better
choices - primarily, switch-case. As someone else noted, this is
basically a structured form of a computed-goto that has the
distinct advantage of limiting the number of directions to which
you can jump.
